Specification of Letters Patent.

Application filed February 18, 1908. Serial No. 416,553.

Patented Mar. 29, 1910.

To all whom it may concern:

Be it known that I, FREDRICK KENOYER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Machines for Making Broom-Covers, of which the following is a specification.

The object of this invention is to rovide a machine for the manufacture 0 paper covers for protecting the brush-portions of brooms, and to perform by machinery all of the operations which have heretofore been done by hand, including the folding of the the cover, the insertion of suitable draw-strings, the cutting off of the paper and the cutting off of the strings.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which Figure l, is a top plan view of my invention; Fig. 2, a longitudinal vertical central section of same; Fig. 3, a vertical cross section on the line 3-3 of Fig. 2; Fig. I, a cross section on the line 4-4 of Fig. 2; Fig. 5, a detail in vertical section of the discharge end of the machine on a larger scale than that shown in Fig. 2; Fig. 6, a detail in perspective of one of the devices for holding the end of a drawstring after the insertion of the string through the paper; Fig. 7, a view in side elevation of the upper feed-roll at the discharge end of the machine; Fig. 8 detail showing the major portion of one of the guide-plates for movement longitudinally of the rolls for adjustment to various widths of covers; Fig. 9, a detail showing the major portion of one of the bearing plates for all of the rolls Fig. 10 a detail in perspective showing one of the twine cutters; Fig. 11 a view showing one of the side surfaces of a broom cover made by my machine. Fig. 12 a perspective view of the device which folds over the edges of the paper to form the cover; Fig. 13 a detail in longitudinal section of the rolls for starting the folds along the edges of the paper before reaching the device shown in 14 is a detail in vertical section of a modified device for forming the corrugations in the paper from which the cover is to be made, preparatory to the insertion of the draw string.

21 re resents the main shaft of my mechine w llCll is mounted transversely of the frame near the discharge end of the machine, in suitable bearings secured to the underside of the horizontal members 22. The members 22 extend longitudinally the entire length of the machine.

24 are bearin plates for a double series of horizontal rollers 25 and 26, and also for a pair of feed rolls 27 and 28' located at the discharge end of the machine. The roll 28 is mounted on the shaft 29, and this shaft has a mutilated pinion 30, see dotted lines in Fig. 5, on one end of said shaft. This mutilated pinion has cogs which engage with cogs on a large cog wheel 32 which is also mutilated to impart an intermittent movement to the pinion 30 and through its shaft to the roll 28. The roll 27 is mounted on shaft 33, and the shafts 29 and 33 are geared together by means of the cog wheels 34 and 35, respectively, on the opposite side of the machine from pinion 30.

37 represents a drum on which a roll of paper to be made up into broom covers is mounted. This paper 39 is fed first to mechanism which will be hereinafter described, for folding the edges of the paper in upon itself for the purpose of strengthening said edges when completed into a cover, and from these folders the paper 39 is fed to and between the double series of rollers 25 and 26, and between the last named rollers to and between the pair of feed rolls 27 and 28. The feed rolls will be set close enough together to on 'age the paper 39 by friction and draw it etween them by the rotation of the rolls, and through the double series of rollers 25 and 26. The rollers 25 in that series will extend for a distance equal to about half of the diameter of the rollers between the rollers 26 of the series below whereby, the paper 39 passing between the two series will be corrugated in the manner shown in Figs. 2 and 5. The axes of the rollers and 26 are in two respective paral lel planes approximately, or perhaps some-' what more than half of the diameter or radius of the rollers apart. The rollers 25 and 26 in both series are provided with annular grooves 40 which register throughout both 'series'and are located at the centers of the rollers, and with the like grooves 41 located at the ends of the rollers, and as the same rollers will be used for the manufacturer of broom covers of three difierent widths the 'grooves4'1 will be made in triplicate on the ends of each roller at the required-distances from thetentergrooves 40.

These grooves, by registering, afford a passa 'eway between all the rollers of the two series for'needles 44 which will be inserted therethrough, andby such insertion will be passed through the corrugations in thepaper 39 produced by said rollers. The outerv or free endwh'i'eh is the sharp or pointed end of the needle is provided with an eye 45 through which a string'46 is threaded. This string is carried through the corrugations of the paper by'the needle and is held after it has been passed through the'rollers, while the needle is withdrawn, thus leaving the string sewed through as a drawstring in the finished broom cover.

48 are guide rods supported on suitable standards above the horizontal frame member 22, and 49 is a transversely extending bar which is slidably mounted on the guide rods 48. To'the underside of the bar 49 the short plates 50 are secured by means of bolts 51,there being between the bar 49 and each plate 50 one of the needles 44 is clamped. The bar "49 and clamp '50 are each provided with transverse grooves in which the needle 44 is held against lateral displacement. The bar 49 is provided on its upper face witha double pair of ears 54 to which the bifurcated ends" of a pitman 56 are connected. The 'pitman 56 has its'opposite end pivotally attached to the lower end of a swinging arm 57. The swinging arm 57 is connected b'y'means of the rod 58 with crank .59 in the shaft 60. The shaft 60 is mounted above and parallel with the main drivingshaft 21 of the ma-.

chine and is intermittently driven by the engagement of the teeth of a mutilated pin-- ion-62, mounted "on shaft'60, with the properly placed teeth on the double faced 'mutilated wheel '32. Bydouble faced, I mean that the wheel 32 has its periphery provided with two-sets of teeth one of which, the outer one engages with the teeth on mutilated pinion'62 and the other or innerof which 'engages with the teeth on the mutilated pinion 30.

The mechanism here described imparts a reciprocatingmovement to the. bar 49 on the guide'rods '48 which in turn impartsa longitudinal reciprocating movement to the sage of the paper to be used two bolts to each plate, and.

three needles 44 carried by said bar 49. Located at the inner ends of the bars 48 is thetransverse bar 64 which forms a support for the twine holders 65, which are secured to the bar 64 by bolts 68. The bolts securing the two outer holder's pass through longitudinal slots 69 in the bar 64 to permit said outer holders to be adjusted longitudinally of the bar to correspond with the position of the outer needles carried below by the bar 49. Twine or 'string'carried in the holders is carried through side openings near the bottom of the holder to their respective needles through the eyes of which the string is threaded and is carried through the paper corrugations formed by rollers 25 and 26, to and through the roll 27 at the discharge end of the machine. This roll 27 is provided with notches 73 to "allow the pasthe threaded needles. 1

Located adjacent to roll 27 on the outside of the machine are holders for engaging and retaining the ends of the strings after the latter have been carried through by the needles. These holders are shown to the best advantage in Figs. 5 and'6. As shown in Fig. 6 when the needles start back after having carried the strings through the corrugated paper it will cause the formation of a loop or bend, and it is this bent portion which is engaged by the said holders. These holders comprise for each string a pair of jaws 79 and=80 operating on a stationary bar 81 fixed transversely of the machine. The jaw 79 is held in fixed position on bar 81 and the aw 80 is slidingly mounted on said bar. The jaw 80 is attached in a fixed manner to a longitudinally movable rod 88. The rod 83 has abent end 84 which lies in the path of a cam-lug or extension 86 on the outer side of the wheel 32 whereby by the rotation of the wheel 32 the cam-lug will move the rod 88 in an outward direct-ion thereby compressing spring '87 placed around the rod 88 between the head of aw 80 and a lug 89 on bar 81. After the cam-lug on wheel 32 has passed the bent end 84 of rod 83 the spring 87 will return the j aw 80 to position in contact l'with jaw 7 9 thereby clamping the bend of the string between-them. To make this engagement more positive I make the jaw 7 9 narrow and bifurcate the jaw 80 to receive the jaw 79 between its two forks, as clearly shown in Fig. 6.

The folding'over of the edges of the paper materialto reinforce said edges before the outer draw strings are placed, is accomplished as a first step by passing the paper from roll 37 between two rolls, the under one 90 of which is as much shorter than the 7 width of the paper as it is desired to fold the edges of the paper, and the body of the upper roll' 2 is of substantially the same length as the roll 90 but it has at each end an additional flange 93, the inner edges of which flanges are made sloping as shown in Figs. 1 and 13, and act in conjunction with the roll 90 to bend the edges of the paper down in the direction of the ends of said roll 90 thereby forming initial portions of the folds. From these rolls, as shown in Fig. 2 the bent edges of the paper pass through plates 95 which bring the folded edges into loose contact with the body of the sheet, and then the folded edges are passed between pressure rollers 96 and 97 which press the loose edges tightly upon the face of the paper. The plates 95 each have a horizontal member and an integral mem her which is at right angles to the horizontal. member at that end where the bent pa er enters andis approximately parallel with said horizontal member at the opposite end of the latter, as shown in Fig. 12. The shaft on which the upper pressure roller 96 is mounted also carries a sprocket wheel 100 (see Fig. 1) which is connected by link belt 101 to sprocket wheel 102 mounted on shaft 21 whereby said roller 96 is positively driven.

After the needle has returned from carrying the string through the corrugated paper, the string is cut off between the eye of the needle and the twine holder by means of cutting knives such as are illustrated in Fig.10 and which are very similar both in construction and operation to the twine holders illustrated in Fig. 6. Instead of the as in the case of the twine holders the head 103 of my cutting lever is released after eration of sewing the draw holding members depending from the heads, heads 79 and 80 of the device has the depending blade 104, and the movable head 105 has the depending blade 106 which is made by the movement of the head 105 to act in cutting conjunction with the blade 104 by longitudinal movement of rod 107 to which the head 105 is secured in a fixed manner. The rod 107 is attached at one end to lever 108 (see Fi 1), which lever is pivoted at 109 to the frame of the machine and has its free end terminating in the path of cam-lug 110 on the inner side of the main wheel 32. By contact of cam-lug 110 with lever 109 the rod 107 is moved out longitudinally in the direction of lever 108 thereby opening the cutters, and when the passing the cam-lug 110 springs 112 will move rod 107 in direction to bring the blades 104 and 106 together so as to cut off the twine. As shown in Fig. 10 the needle 44 has been withdrawn through the cutting blades from the corrugated paper through which it has just sewed the draw string. After the twine or string has been cut oif its end remains threaded through the eye of the needle and upon the separating of the blades 104 and 106 after severing the string the needle will be moved forward between the blades in the next opstring through the aper. It will thus'be seen that the need e 44 always remains threaded.

Secured to the frame 20 of the machine at the delivery end of the latter are a pair of guide plates 114 having vertical grooves 115 in which the ends of a paper cutting knife 116 are mounted, and by which said knife will be compelled to move in a vertical direction. The knife 116 works in conjunction with the stationary knife 11.8 which is bolted to the plates 114, see Fig. 5. Supported by frame 20 are the bell cranks 120 having their lower arms connected by link bars 121 with the knife 116 and the upper arms of the bell cranks are pivotally connected with the eccentric rod 124. The rod 124 is operated by the eccentric 126 mounted on the shaft 60. See Fig. 2. The above described mechanism will reciprocate the knife 116 so as to cut off the paper in required lengths to form broom covers. This severance of the paper occurs between those stitches where the cuts have been made in and to prevent the cutting off of the ends of the draw strings by the aper cutting knives I provide brushes 128 for rushing the stringends forward out of the path of the knife 116. The brush handle 130 is connected by means of a hinge joint with an extension 131. The handle extension 131 is pivoted to the hanger 132 and has a sliding sleeve 133 on its outer end. This sleeve 133 is connected pivotally with hanger 134, which hanger is supported by the horizontal portion of a bracket-bar 135 which is attached to and moves up and down with the knife 116. The brush handle 130 is pivotally connected to the link-bar 137 and the latter is pivotally connected with hanger 138. By the above described mechanism the upward movement of knife 116 will cause the brush handle 130 and extension 131 to approach longitudinal alinement with each other thereby forcing brush 128 back between the knives 116 and 118 to the position shown in Fig. 5, and the lowering of the knife 116 will cause the handle 130 and extension 131 to assume the position shown by the dotted lines in Fig. 5 which will cause the brush 128 to move forward with a sweeping movement to its position shown by dotted lines in Fig. 5 which will sweep the ends of the strings forward out of the path of knife 116.

The hangers 132 are mounted on a bar 140, the hangers 138 on bar 141. The bars 140 and 141 are supported by plate 114, said plate being suitably extended to receive the bar 140. The hangers 132, 134 and138 are adjustable longitudinally on their respective supporting bars for the purpose of changing the positions of the brushes to suit the changed positions of the strings when the machine is correspondingly changed to manufacture narrower or wider broom covers.

the draw strings made.

Attention has been previously called to the triplicate grooves in the ends of rollers 25 and 26 and-of the feed roll 27 for the purpose of adjusting the machine to make broom covers of different widths. In order to properly guide the paper between the rollers 25 and 26 I provide the two plates 1&5 (see Figs. 3 and 8) which will be set so as to contact with the side edges of the paper passing between the rollers and their positions will depend, of course, upon the width of cover to be The plates have circular openings 14:6 through which the rollers will loosely pass.

In adjusting the machine to manufacture broom covers of different widths it is necessary to change the positions of the needles, also of the twine holders at the delivery end of the machine, of the twine cutters and the twine holders and also to change the lengths of the rollers 90 and 92 which assist in folding the edges of the paper. The variations of the lengths of rollers 90 and 92 is secured by constructing said rollers in telescoping sections as shown in Fig. 13 which permits said rollers to be made longer or shorter as circumstances may require.

The paper from which the broom covers are to be made is fedfirst from drum 37 through the device for folding the edges of the paper under, and then the paper with its edges thus folded is fed between the rollers 25 and 26 which corrugates the paper for the purpose of enabling stitches to be formed by passing the needle through the paper from one end of the horizontal set of rollers to the other. Then after the draw-string or twine has been stitched through the paper in this manner the ends of the strings are caught by .the twine holders and are held by them while the needles are withdrawn from the paper. The strings are cut off after the needles have moved back of theknives for that purpose, andthe previously sewed cover, still intact with the paper of the roll, is cut off. The several parts of the machine are timed by wheel 32 to operate at their proper intervals.

While I have shown a double series of rollers 25 and 26 for the purpose of corrugating the paper preparatory to inserting of the draw-strings by the aid of the needles. there are other means for securing the same conditions of the paper, such, for example, as by the use of a pair of corrugated plates 160 and 162, as shown in the modification illustrated in Fig. 14, and I therefore do not wish to limit my invention to the mechanism shown.
